  • 0

When using Mercurial, how do you undo all changes in the working directory since the last commit? It seems like this would be a simple thing, but it’s escaping me.

For example, let’s say I have 4 commits. Then, I make some changes to my code. Then I decide that my changes are bad and I just want to go back to the state of the code at my last commit. So, I think I should do:

hg update 4

with 4 being the revision # of my latest commit. But, Mercurial doesn’t change any of the files in my working directory. Why not?

    hg revert will do the trick.

    It will revert you to the last commit.

    --all will revert all files.

    See the link for the Man Page description of it.

    hg update is usually used to refresh your working directory after you pull from a different repo or swap branches. hg up myawesomebranch. It also can be used to revert to a specific version. hg up -r 12.
